Hi Matty,
yes, Souffle and Basia have said what I was trying to get at. Normal levels of noise and light are fine, and as they grow they need to get used to living in a home environment.
Keeping it really quiet can be useful for the first week or so, mainly so as not to disturb Mum and to stress her in any way as she gets used to having her new babies.
I know keeping them in a bedroom for the first week helped our Princess who now has 13 fat pups running around and has moved back into our fairly noisy hamster/living room! (and as for noise, they now can make more than my two teenage daughters do
) well- maybe not, but they spend a lot of time talking to each other and telling each other off - plus telling Mum "I'm hungry"
